IMPROVEMENT IN WAGON-SEATS.

Specification forming part of Letters Patent No. 167,388, datedSeptember 7,1875; application filed August 13, 1875.

To all whom it may concern:

Be it known that STEPHEN B. (JONOVER, of Jersey city, in the county ofHudson and State of New Jersey, have invented a new and ImprovedSpring-Support for VVagon- Seats, of which the following is aspecification:

Figure l is an inner face view, partly in section, of my improvedspring-support for wagon-seats. Fig. 2 is a side view of the same; andFig. 3 a top view of the same.

Similar letters of reference indicate corresponding parts in all thefigures.

The object of this invention is to produce a spring-support forwagon-seats, which can be cheaply gotten up, and which will neverthelessbe perfect in all its parts and in its operation.

As heretofore constructed the spring-supports were of two kinds, thefirst and oldest being adapted to elliptic springs, and the later stylesto vertical spiral springs. The elliptic springs are not desirable onordinary wood wagons, because they are liable to cause a jerking andviolent motion of the seat, since they are not guarded against side orend motion. For the spiral springs, complicated and costly connectionshave heretofore invariably been used. Such spiral springs were alwaysapplied singly at each end of the seat.

Now, my invention consists, first, in constructing the supporting-framewith two ver tical tubes that are partly closed at the bot tom, and incombining therewith two vertical pins, having shoulders at their upperparts, which pins are cast in one piece with the plate to which the seatis fastened. My invention also consists in applying a guiderib to theupper plate, and in forming a groove for the reception thereof on theface of the supporting-frame.

In the accompanying drawing, the letter A is a vertical plate, which ismade with screwholes, or with a top flange, a, or otherwise soconstructed that it can be readily fastened to the side of a wagon.

which are open at their upper ends, but

This plate is made in one piece, with two vertical tubes, I),

partly closed at their lower ends, as indicated in Fig. 1. The plate A,made in one piece with the tubes I) b, I term the support I ing-frame ofthe spring-support, because it is fastened to the wagon-body, and servesto support the other parts of the seat. B is a top plate, to which theend of the seat is fastened. This plate is made in one piece, orotherwise intimately connected with two vertical pins, (1 d, which areas far apart as the tubes b b, and which enter said tubes, as shown.Each pin d has an enlarged upper part or head, 6. into each tube 1) isplaced a spiral spring, f, which embraces the smaller lower part of thepin (1, and is lengthwiseconfined between the partly-closed lower end ofthe tube and the head 6 of the pin. The lowermost end of the pin 01 hasa shoulder or other enlargement, whereby it is prevented from beingraised entirely out of the tubes b.

By the construction or devices, as heretofore described, I am enabled toproduce a seat-support much less expensive than those heretoforeproduced or devised, and one which, by having two guide-tubes, pins, andsprings will have a much steadier motion, and require'much lightersprings, than the ordinary spring-supports now in use. For relieving thepins cl and tubes 1) of all unnecessary friction, I have formed avertical guide-rib, g, on a pendent back plate, h, of the plate B, andhave made the plate A with a. vertical groove, i, into which the rib genters, as shown more particularly by dotted lines in Fig. 3. By thisrod and grooved guide the vertical motion of the plate B and seat isinsured, and the actual working parts of the spring-supportb, (Z, and fare relieved from all unnecessary strain.

It is evident that instead of forming the rib g 011 the plate B it mayas well be formed on the plate A, in which case the groove "i is formedon B, the effect being equal.
